The way I think of a film SLR (as well as a DSLR I guess) is that you'll definately have no problem capturing most/all photos you want to take with it. Some people like Mark have supplemented a high zoom digital into the picture which can really help out as he already pointed out
(in terms of money, pleasure, whatever...).
The only problem with film (at least for me) is the SCANNING! Its such a bitch to have 19+ rolls of recent film to scan, and also have some problems with the scanner (these vertical streaks on some that require cloning/dodging)- so then it takes forever just to process an average shot to HQ
level, then on top of that to have it rejected for "badscan" (which is true i guess in some situtations, lol)
But shoot however it suits your needs- personally I'm content knowing in the future I can buy a top of the line scanner and scan most of my old photos with ease. No rush mon.
Anyway... bottom line is that I suggest getting some sort of SLR.
